在河南、山西、甘肃三个纬度相近而温度差异较大的试点，对９０个谷子品种的出苗到抽穗日数进行了研究。结果表明，各品种之间出苗到抽穗所需温度差异很大，且不同来源的品种对温度的敏感程度也不同。明确了我国谷子主产区各生态区主要推广种的感温性，并筛选出４个对温度不敏感的品种和４２个较不敏感的品种。
In three pilot stations, Henan, Shanxi and Gansu with similar temperature differences, the number of days from emergence to heading of 90 millet cultivars was studied. The results showed that the temperature difference between the emergence and the heading of different varieties was very different, and the varieties of different origins were different in temperature sensitivity. The temperature sensitiveness of the main popularized species in each ecological area of the main producing areas of millet in China was clarified, and four varieties that were insensitive to temperature and 42 less sensitive varieties were screened out.
